Title: Phase reversal detecting circuit
Inventor: KITAGAWA YOICHI
IPC: H02H7/097
Filed: 1987-01-19
Abstract: PURPOSE:To enable phase reversal detection and open phase detection by providing a means which resets the operation of a FF at the time of reversed-phase input and an open phase with a reset signal obtained by delaying a 2nd phase signal from a 2nd phase detecting means. CONSTITUTION:The output of a photocoupler PC1 is supplied to the clock pulse input terminal CK of the FF 1. The output of a photocoupler PC2, on the other hand, is supplied to a terminal A of a monostable multivibrator M1 through an inverter G2 and the output (e) of the monostable multivibrator M1 is supplied to a terminal CK of an FF 2. When there is a reversed-phase input, the phase of a phase signal (c) leads a phase signal (d) by 120 deg. and the reset signal (g) is at 'H' when the signal (c) rises. Therefore, the FF 1 does not latch a voltage +V even when inputting the signal (c) and a detection output (i) is still at 'L'. Further, when, for example, a T phase is open, an S-T phase voltage (b) is 0V, so the signal (d) is also held at 'L' as it is. The signal (g) which is the Q output of the FF 2 is at 'H' and the Q output of the FF 1 is still at 'L', so that the output (e) falls to 'L'.

Title: Semiconductor device
Inventor: YOKOTA ETSUO
IPC: H01L21/316
Filed: 1982-01-27
Abstract: PURPOSE:To improve the pressure withstanding property and yield by a method wherein the Zn base glass filled in mesa grooves of wafer is covered with highly heat resistant organic film.

Title: Positioning controller
Inventor: HIGOMURA MAKOTO
IPC: H01L21/027
Filed: 1986-01-23
Abstract: PURPOSE:To shorten positioning time and to improve positioning accuracy by raising a loop gain as deviation is smaller so that a position deviation voltage generating the prescribed motor torque can be outputted. CONSTITUTION:In terms of position control, gain data in a gain setting table 39 is read out every fixed time in accordance with a value counted by a counter 41 counting a timing clock from an oscillator 40, and stored in a register 36. A multiplier 34 multiples an analog position deviation voltage outputted from a D/A converter 5 by the gain data stored in the register 36 by a voltage that a D/A converter 35 converts into analog. Thus the position deviation voltage is multiplied by the gain data. Namely, the loop gain of a control system is changed according to the gain data. Thus the positioning time can be shortened and constant position deviation can be reduced.

Title: Disk player
Inventor: KATO KIYOSHI
IPC: G11B21/08
Filed: 1994-02-03
Abstract: PURPOSE:To reduce the mistakes in track jumping and track counting. CONSTITUTION:By utilizing the fact that a sinking part arises on the level of an RF signal and then an FOK signal capable of focus setting becomes a low level when a pickup 3 passes through a scratch, etc., attached on a disk 2, track jumping is inhibited so long as the FOK signal is low level.

Title: Grounding point discriminator in variable speed operation system
Inventor: JOFU TOSHIAKI
IPC: H02P5/74
Filed: 1988-01-22
Abstract: PURPOSE:To enable an accident generating section to be quickly detected, by detecting the grounding accident of a motor, and by enabling a grounding point to be discriminated through the lit state of a display element before excess current is generated. CONSTITUTION:When output is transmitted to a comparator CP, then the working of an oscillator T is started, and the oscillating output is counted by a counter CUT. When the AND requirements of the output of the counter CUT and the output of the oscillator T are fulfilled, then output for turning switches OFF in order just for a short time is transmitted from a first output section FT. When the switches are in an OFF-state and when ground current is reduced and the output of the comparator CP comes to nothing, then the oscillating working of the oscillator T is stopped. As a result, the output of the counter CUT is set in a retained state, and ground phase discriminating display elements HD2-HD5 are lit.
